To all whom it may concern:

Be it known that I, LOUIS A. WARREN, a

I citizen of the United States, residing at Hodgenville, in the countyof Larue and State of Kentucky, have invented new and usefulImprovements in Building Blocks, of which the following is aspecification.

This invention relates to building con- Struction, particularly tobuilding blocks, and has for its object the provision of a buildingconstruction embodying the use of metallic plates or sheets adapted tobe secured upon the frame of a building and peculiarly corrugatedwhereby to provide looking means for holding specially formed blocksadapted to be disposed in courses and so formed that the successivecourses when engaged upon the corrugated sheet will operate to secureeach proceding course.

An important object is the provision of blocks of this character whichmay be formed of plastic material such as cement or the like when theiruse is desired for exterior work or which may be formed as tiles orbricks for either exterior or interior work or which may be" formed ofany suitable composition or even of wood alone for interior trimmingaround fire places, bath rooms, or any other desired location.

Another object is the provision of blocks of this character which may beformed plain or which may be rough or ornamented in any desired manner,depending upon the character of the work.

A further object is the provision of blocks of this character which havetheir engaging edges interfitting whereby not only to serve asinterlocks but also to serve for excluding moisture from the building.

An additional object is the provision of a building construction of theabove mentioned character which will be simple and inexpensive, whichmay be assembled even by unskilled labor, which will be eflicientanddurable, the art.

With the above and other objects and advantages in view, the inventionconsists in the details of construction to be hereinafter more fullydescribed and claimed, and illustrated in the accompanying drawings inwhichv p v Figure 1 is a fragmentary elevation and a general improvementin cation of my invention, Figure 2 is an elevation of a.plurality'- oflnterengaged blocks,

igure 3 is the line 3-3 of Figure 2, and

Flgure 4 is a vertical sectional view on the line 44 of Figure 2.Referring more particularly to the drawlngs, the letter A designates abuildin foundat 1on upon which is-mounted a sill from whlch riseuprlghts C which may beeither of wood or metal.

In carrying out my building construction I make use of sheets or plates10 formed of sheet metal of suitable gage and these plates are securedupon the upright C in end to end relation and held in place thereon bysuitable fastenings which might be screws or bolts, depending uponwhether the uprights 0 are of wood or of metal and the sheets areprovided with holes 11 for the passage of such securing members. Eachsheet 10 is formed with corrugations 12 which are V-shaped incrosssectlon and are inclined upwardly whereby to rovide overhanginglocking ridges.

fter the sheets 10 are secured in position,

I dispose upon them blocks 13 which may be formed of any suitablematerial and of any desired dimensions. The blocks are arranged incourses with their joints staggered, as clearly shown and in accordancewith the well known masonry construction. As shown in Fig. 1 each courseis associated with one of the corrugations 12 though I prefer toassociate each course with two corrugations as shown in Fi 4. The blocksin this figure are designate by the numeral 30 and the corrugations by36. Upon its rear face each block is formed with a pair ofIongitudinally extending ll-shaped recesses 37 engaged upon thecorrugations and each defining a retaining shoulder engaging behind theoverhanging portion of the corrugation or ridge. The upper and loweredges of the blocks are inclined, as shown at 31 and the inclination isdownward and outward with respect to the base sheet. The purpose of thisinclination is to cause a lockin action of a building frame showing theappli-' between the successive courses 'so t at the.

blocks will be held firmly onto the sheets or plates without theemployment of any addia plurality of spaced tional securing means.Another advantage though meetin ends'of the blocks as formed withmterfitting ribs and grooves, the ribs and grooves alternatin as shownand the former belng desi nate by the numeral 33 and the latter by t enumeral 34.

In finishing around corners and the like,

- it is understood that the same general design of construction may beemployed in the 'formation of corner blocks though such are notillustrated.

From the foregoing description and a study of the drawings it will beapparent that I have thus provided a simple buildm structure involvingmetallic base plates an tiles readily engageable thereon andautomatically lockin one another in position. It will be noted t at.owing to the simplicity and ease of application a building ma beconstructed frommy blocks and sheets y ahave shown the meeting ed es andcomparatively unskilled person so that a great saving in time and laborand cost of construction will be effected.

. is of course to be understood that I reserve the right to make-suchchanges in the form, construction, and arrangement of parts as will notdepart from the spirit of the invention or the scope of the subjoinedclaim.

1Having thus described my invention, I 0 mm:

A wall construction comprisin a metallic sheet provided with a series 0longitudinally extending corrugations having sharp edges, the upper wallof each corrugation being inclined upwardly with respect to the sheet todefine an overhanging flange, and a plurality of blocks disposed uponthesheet and. provided on their rear faeesin s aced relation to the edgeswith longitudina y extending grooves of the same cross sectional contouras said corrugations and defining retaining shoulders en a 'ng behindsaid overhanging flan es, an t e edges and ends of said locksa1 beingbeveled and formed with tongues and grooves having interfit- 'ting engaement, the upper and lower ed es being inc ined downwardly and outwardly.

In testimony whereof I afiix 111 Si nature,

LOUIS A. a AR EN.
